Mexico Opens Its Grid to Competition

As part of a wider reform of its energy market, Mexico is privatizing its energy regulator and will begin allowing private companies to sell energy to, and add capacity to, its electricity grid.

Petroleum and electricity have been state monopolies in law since the 1917 constitution and in practice since the late 1930s, when Mexico succeeded in expropriating foreign energy firms’ holdings.

What Do Women in Engineering Want?

For years, psychologist Nadya A. Fouad of the University of Wisconsin in Milwaukee has been asking women in engineering what they want. She and organizational psychologist Romila Singh, also at U-W Milwaukee, conducted a National Science Foundation-supported survey asking over 5,000 female engineers their reasons for leaving—or staying—in the field. On Saturday, 9 August, at the American Psychological Association annual meeting in Washington, D.C., Fouad presented their latest analysis of that data. Those who leave, she reports, turn out to be just as confident and successful as those who stay. They may, however, be more likely to have encountered belittling or undermining from colleagues and a lack of support from their supervisors.

For something that took years to arrive, Madrid’s public bicycles sure get off to a fast start. Pedal once and the 36-volt, 10-ampere, electric motors will give you a sudden boost. Going up one of Madrid’s many hills, it is a welcome aid. Downhill, the burst jars. But riders can disable the boost by not pedaling, and moderate it with electric controls on the handlebars. With a little practice, the bikes begin to feel like underpowered motor scooters. “Our major goal is to move journeys that are now done by car to the bicycles,” says Elisa Barahona, Madrid’s director of sustainability and environment.
